Whether or not you know anything about mining, you need to have some powerful hardware.
You could mine with a basic computer that only has a processor, like an Intel or AMD processor. But graphics cards that PC gamers use to power their games are much better suited for the job.
For the best results, you'll need desktop PC and Nvidia or AMD graphics cards. Laptops, even the gaming variety, may not be very well suited for mining.
For Nvidia cards, you're better off with the current GTX 1000 series of graphics cards, like the GTX 1060 (6GB model) or above.
As for AMD cards, the best models include the RX470, RX480, RX570, RX 580 (8GB model), RX56, and RX64. But good luck finding an AMD card at any sort of reasonable price these days.
